Multicenter Study
Primary graft failure following lung transplantation: predictive factors of mortality.
To assess incidence, outcome, and early predictors of mortality for patients with primary graft failure (PGF) following lung transplantation (LTx), and to develop an injury severity score able to accurately predict ICU mortality for these patients. ⋯ PGF following LTx is a frequent event, with significant ICU morbidity and mortality. We demonstrate that four simple factors allow prediction of ICU mortality with good accuracy.

Aboriginals in Canada bear a disproportionately higher burden of some chronic illnesses than nonaboriginals. Although there is a greater prevalence of smoking, poor housing, and overcrowding in aboriginal than nonaboriginal communities, the rates of office and emergency visits for asthma and COPD among aboriginals are not well known. ⋯ These findings indicate that aboriginals bear a disproportionately higher burden of asthma and COPD than nonaboriginals. However, lower use of spirometry and specialist services suggests that there might be access barriers to quality health care for aboriginals in Canada.

Meta Analysis Comparative Study
Replacement of oral corticosteroids with inhaled corticosteroids in the treatment of acute asthma following emergency department discharge: a meta-analysis.
Oral corticosteroids (CS) are standard treatment for patients discharged from the emergency department (ED) after treatment for acute asthma. Several recent, relatively small trials have investigated the replacement of CS with inhaled corticosteroids (ICS), with varied results and conclusions. This systematic review examined the effect of using ICS in place of CS on outcomes in this setting. ⋯ There is some evidence that high-dose ICS therapy alone may be as effective as CS therapy when used in mild asthmatics on ED discharge; however, there is a significant possibility of a type II error in drawing this conclusion.

To determine multilevel likelihood ratios for pleural fluid tests that are commonly used to discriminate between exudative and transudative pleural effusions. ⋯ Multilevel likelihood ratios combined with a clinician's estimation of the pretest probability of an exudative effusion improve the diagnostic accuracy of discriminating between exudative and transudative pleural effusions. Likelihood ratios avoid the use of confusing terms, such as "pseudoexudates," that derive from the use of single cutoff points for pleural fluid tests.

To evaluate the potential coerciveness of clinical research trial (CRT) acronyms, and to make clinicians aware that some CRT acronyms may be coercive to research subjects by subliminally enticing or outwardly promising something that the CRT may not be able to deliver. ⋯ A distraught or frightened patient with a life-threatening illness who is offered a research study with an acronym of CURE, HOPE, HELP, IMPROVED, LIFE, RESCUE, MIRACL (sic), SAVED, or ALIVE is possibly being coerced by the acronym. Institutional review boards (IRBs) and the medical research community would not tolerate a CRT entitled, "A Surefire Cure for Cancer." They should be no more tolerant of a CRT with an acronym listed above. It is time for researchers, sponsors, and IRBs to take a more responsible approach to potentially coercive CRT acronyms and discourage or prohibit their use.
